Applies to: Xbox Series X/S and Elgato 4K X; 1080p60 SDR baseline capture, with documented 4K60 NV12 USB-link comparison.
- video
- Xbox HDMI OUT → 4K X HDMI IN → HDMI OUT → TV input
- data
- 4K X USB-C → computer USB 3.2 Gen 2 data port → supported capture application
- power
- Console, TV and computer use their own supplies. Capture USB is not a TV power supply.
What the path requires
- Two HDMI cables and a USB data cable appropriate to the selected capture rate; use the exact 4K X input/output directions.
- For the documented Windows host class: Windows 10 64-bit, sixth-generation Intel Core i5 or AMD Ryzen 5 3600 or better, NVIDIA GeForce GTX 10xx or better, and at least 8GB RAM. The source also specifies dual-channel Windows RAM.
- For the documented Mac host class: macOS 11 Big Sur or later, Apple M1 or fourth-generation quad-core Intel Core i5/comparable hardware, the stated graphics support and at least 8GB RAM. This is a minimum host class, not approval of an unnamed computer.
- Use USB 3.2 Gen 2 for the scoped 10Gbps capture case. Gen 1 has reduced capture options. Confirm the selected codec/rate in the matrix rather than inferring it from the USB-C form.
- Select the capture application and its own applicable requirements. Elgato says OBS, XSplit, Streamlabs Desktop and other applications can differ from 4K Capture Utility. No application installation or current version has been tested here.
Read the matrix in the right direction
Input/passthrough columns describe what arrives over HDMI. Capture rows describe the USB output to software. A dash permits passthrough without that capture format. The app can impose further limits.
Elgato Game Capture 4K X — Supported Resolutions and Frame RatesOne precise mode comparison
Elgato lists 3840×2160 at 60fps NV12 8-bit 4:2:0 on USB 10Gbps and 30fps on USB 5Gbps. The selected capture codec matters even when the TV still shows the original 60Hz picture.
Elgato Game Capture 4K X — Supported Resolutions and Frame RatesA computer requirement is separate from the HDMI mode
The official system-requirements article qualifies the host OS, processor, graphics, RAM and USB path. Use that host-class check before selecting the supported capture format, then check the actual application's requirements. A passing TV picture or a recognized USB device does not establish the computer's recording capacity.
Elgato Game Capture 4K X — System RequirementsWorked documentary examples
1080p60 SDR game recording
Documented outcome: Within the published matrix
- Unprotected game signal, supported computer/app, direct USB data connection.
- Confirm the TV receives the console picture.
- Add 4K X as the video source in the application and select 1080p60.
- Check audio level and a short local recording before a session; that check has not been performed here.
Protected streaming application
Documented outcome: Documented conflict
- HDCP-protected HDMI signal.
- Stop capture of protected content; use the service’s supported playback route.
- Do not defeat HDCP.
4K60 requested, computer USB port unknown
Documented outcome: Missing evidence
- No exact USB link or codec information.
- Identify the computer port/link and selected app format.
- Compare that complete tuple with the codec table before diagnosing the HDMI cable.
Your next useful observation
Write source output, TV reported mode, capture format and negotiated USB link as four separate observations.
Keep these limits
- No capture, audio latency, frame-drop or USB-rate measurement.
- Analog 3.5mm on 4K X is line-in, not a microphone input.
